I figured out the particle systems... But the textures...
I was able to make him invisible... But as soon as i look at him ingame it crashes...
What I did was going to the .dae folder and changing some "servant_grunt" to "fog_spirit", in places i thought was right... probably not.
<material id="fog_spirit_hair_material" name="servant_grunt_hair_material">
<instance_effect url="#servant_grunt_hair_material-fx"/>
</material>
</library_materials>
<library_effects>
<effect id="servantgrunt_material-fx">
<profile_COMMON>
<newparam sid="servantgrunt_dds-surface">
<surface type="2D">
<init_from>fogspirit_dds</init_from>
<format>A8R8G8B8</format>
</surface>
</newparam>
<newparam sid="servantgrunt_dds-sampler">
<sampler2D>
<source>fogspirit_dds-surface</source>
Trying is the first step to success.
